GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent N o. 472,143, dated April5, 1892. Application ledl January 30, 1891. Serial No. 379,744. (Nomodel.)

To all whom t may concern:

Be it known that I, GEORGE SCHUBERT, a citizen of the United States,residing at Walnut,in the countyof Bosque and State of Texas, haveinvented certain new and useful Improvements in Grain-Binders; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, suchas will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improvement in down-binders orplatform-binders, and is especially adapted for the conveyer patentedFebruary17,1S91,No. 446,473, invented by me.

This invention has reference more especially to the compressing,discharging, and starting mechanism for grain-binders.

This improvement relates to the construction and operation of thecompressor, the discharging-bar, and a starting mechanism for thebindergearing, together with other features specified in the claims, soas to adapt to the above-mentioned conveyer the Wellknown Appleby typeof machines-such as is represented, for example, in Letters Patent ofthe United States granted to George Esterly, No. 262,026, dated Augustl,1882, and No. 266,254, dated october 17,1882.

By the above-mentioned improvements the needle can be placed above andthe tying mechanism below in a narrow space in the platform, so that thegrain can be carried by the conveyer direct to and within reach of the`binder arm or needle, thus dispensing with the elevating mechanism andpacking mechanism, as is shown in the drawings, in which- Figure 1 is aplan view of a harvester-platform provided with my improvements, theupper plate of the platform being broken away in various parts to showparts below in full lines. Fig. 2 is a front View of the platform andmechanism. Fig. 3 is a longitudinal sectional view on line 1 1, Fig. 1,the post being partly broken away. Parts beyond the section-line areshown in full lines. Fig. 4 is a cross-section on line 2 2, Figs. 1 and2, looking as indicated by arrow No. 1 in Fig. 1. Fig. 5 is across-section on line 3 3 of Fig. 1 with the cross-sill omitted, lookingas indicated by arrow No. 2 in Fig. 1, showing parts beyond thesection-line in full lines. Fig. 6 is a side view of the diScharger-barshown in position with parts of the upper plate of the platform shown insection. Fig. 7 is a detail lview of the lever on the dischargerprovided with its anti-friction rollers. Fig. 8 is a detail View of thestarting-lever on the shaft CZ and an enlarged plan View of the dogcarried by said lever. Fig. 9 is a plan view of the rod provided withthe block or ferrule carried by the compressor and a plan view of theferrule, and Fig. 10 is a front view of the mechanism with the needleelevated.

A designates the finger-bar of the ordinary Z form. Said finger-bar canbe extended with its stubbleward end to the harvester-frame. (Not shownin the drawings.) A

,l A designates an inclined ange extending from near the inner shoe B3stubbleward a proper distance, for the purpose hereinafter stated. Saidflange A can be constructed as a part of the finger-bar A, orconstructed in a separate piece provided witharight-angled flange a2, bywhich it can be secured to the finger-bar A, as shown in Fig. 1.

a. designates the lower` plate of the platform, secured with its frontedge to the lower iiange of the linger-bar and with its rear edge to thesill B.

a is the upper plate of the platform, secured with its front edge to theupper flange of the linger-bar A and with its rear'edge to the sill B.Said sill B forms the rear sill of the platform, and is provided with aninclined extension at its stubble end to correspond with the inclinedextension A.

The plates a and a extend stubbleward to the ends of the sill B and theflange A', with the plate a curved down at its stubbleward end to partlyclose the stubble end of the platform, as shown. The front edge of theplate d is turned down to a right angle, (indicated at a3 in Fig. 1,) bywhich it can be secured to the inclined flange A. On said stubblewardextension of the platform is placed in an upright position thebinderframeD a proper distance stubbleward from the shoe B3, as shown,and secured in any suitable manner to the finger-bar and the inclinedflange A.

B designates a post extending from the plate a to the plate a and placedon thegrain side ot` the arm D3 with its rear side flush with disk ffl.

t8 is a lever pivoted to the post B6 a proper distance from its lowerend, said lever having its lower end curved forward and a dog or rod t9pivoted thereto. Said rod i projects stubbleward through a perforationin the post B to engage with the stud t5.

t is a stud secured in the upper end of the lever ts, projectingrearward beneath the upper strand of the chain c.

The perforation in. the post B for the rod 9 forms a guide for thestubbleward end ot` the rod t.

l is an opening made inthe platea ashort distance grainward from thepost B and on the front side of the slot A2. A part of the metal is cntloose at both ends. Part IS is curved upward and a part I" is turneddown, as shown in Fig. 6.

I is the discharger-bar provided with two prongs l7 on its free orstubbleward end to more readily engage the bound sheaf and with itsother end extending grainward and bent near to a right angle to near avertical position, forming the part I5, with its lower end rounded toreceive the lever I2, secured by a key lf.

l is an eye in the lever 12 to receive the discharger-bar, as described.Said lever I2is bifurcated at one end and provided with antifrictionrollers 13 and I4 to operate in the track 2 and projecting with itsother end rearward above the lower strand of the chain e. The dischargerrests with its rear or grain end on the plate a and with its free orstubbleward end on the downward-projecting portion l on the plate d whennot in use. rlhe lower fiange of the finger-bar can be extended towardthe rear, as shown in Fig. 4, to form a projection for the track i2.

c' is a strip extending from the lower flange of the finger-bar to theplate a. Said strip is provided with a strip t" on its rear side,forining the track i2, in which the anti-friction rollers I3 and IA1operate.

F designates the compressor. Oneor more of such compressors may beemployed. (One is shown in the present instance.) Said compressor F iscurved about as shown in Fig. 3 with its lower end bifurcated.

J is a perforated block or ferrule provided with studs J, by which it ispivoted in the bifurcation of the compressor F.

J2 is a rod provided with an anti-friction roller J3 on its lower end tooperate on the plate a. Said rod extends through the fer- IIO rule J andis provided with an eye J5 near its upper end to receive theforward-projectin g end of lever j.

J4 is a spring coiled on the rod J2, bearing with its lower end againstthe ferrule J and with its upper end against the shoulder formed by theeye J5. l

,7'4 is a block secured on the lower side of the plate a on the rearside of the slot A2 and near the stubble end of the track 72, as shownin Fig. 3. Said track jg is formed as shown in Fig. 4, having its ends Sand S turned back orrearward, as shown in Fig. 1,and inclined, as shownin Fig. 3, to correspond to the inclined portion of the chain e.

j is a two-armed lever having anti-friction rollersj and j2 on the freeends of its rearward-projecting arms to operate in the track 75. Saidlever j projects forward through the eye J5 of the rod J2 with its endextending to and beneath the upper strand of the chain e.

75 is a spring secured with one end to the sill B (near the stubbleendof the sill) and with its other and free end pressing against the rearof the compressor,as shown in Fig. 1.

The chain e is provided with inwardly-projecting lugs e2, e3, and e4.The lug e3 operates on the studs t and t to operate the startingmechanism and is located on the front edge of the chain e about two feetin front of or stubbleward from the conveyer. The lug e2 is located onthe rear edge of the chain e and is to operate on the lever j to operatethe compressor F and is placed about two feet stubbleward from the luge5. The lug e4 is also located on the front side of the chain e andabout six or eight feet stubbleward from the lug e2 (said distancedepends somewhat on the size of the machine and length of the platform)and is to operate on the lever I2 to operate the discharger-bar I. Saidlug e4 is placed on the lower strand of the chain e far enough from theconveyer or 1ug-c2, so that the grainward movement of the conveyer andupper strand of the chain e ceases as the lug e4 nears the roller o. Thestuds t and t project only to the center of the width of the chain e',and thus are not operated by the lug e2, and the lever j also onlyprojects to near the center of the width of the chain, and thus is notoperated by the lug e2.

The ends of the track i2 are turned back the same as thetrack js, asindicated in Fig. 1.

The plate et is out out at J7 for the operation of the compressorF shownin Fig. 1, and J8 is an opening made in the plate a for the reception ofthe needle shown in Fig. 3.

u isa bracket secured to the under side of the plate a and on the frontside of the slot A2 and near the grain end of the track i2, projectingwith its free end rearward over the chain e and provided with ananti-friction roller u in position to operate on the chain e toguidesaid chain. u is a similar bracket secured to the post B6 with itsanti-friction roller o in position to operate on the lower strand of thechain c. Said bracket v and roller fu and a part of the post B6 areomitted from Fig. 3 to show the construction of the compressor and areshown in Fig. 10.

R is the main operating-arm of the conveyer, pivoted near its'center tothe conveyerblock R4 and provided on its lower end with an anti-frictionroller R to operate on the plate a and having pivoted to its upper endan extension R2.

R3 is a rod pivoted with its lower end to the conveyer-block and withits upper end to the grainward end of the extension R2, as more fullydescribed in the patent issued to me, No. 446,473, dated February 17,1891. The conveyer-block R4 is made about the same thickness as thechain e. Said chain e is secured to each end of the conveyer-block R4with its upper side flush with the upper side of the conveyer-block R4,as shown, to operate under the guide-roller u, as shown.

197 is a spring secured to the bracketC, projecting with its free endgrainward in position to engage with the cogs b9, as shown.

The bevel-pinion b is partly broken away in Figs. 2 and 10 to show partsbeyond in full lines.

The parts are constructed and arranged to operate as follows, viz: Thebevel-pinion b receives its movement from mechanism (not shown in thedrawings) and operates the shaft C, which in turn operates the pinion bby means of the clutch b2. Said shaft C also operates the conveyer bymeans of the sprocket-wheel e and chain e. As the conveyer movesstubbleward with the gavel of grain the lug e2 comes in contact with theforward-projecting end of lever j, moving it stubbleward, therebyshifting the compressor in position, as seen in Fig. 3. As thecompressor receives its proper position the roller t72 will reach theportion S of the track js, thereby moving the lever j to an angle tovthe chain e and back to some extent, allowing the lug e2 to spring thechain e and pass the lever j. As the lever j is moved rearward it alsomoves the upper end of the rod J2 rearward and behind the block j4, (seeFig. 3,) thus preventing the rod J2 from moving grainward when notsodesired. The compressor receives its elasticity of compression from thesprings J4 and L75 and is preferably made of spring-steel of properthickness, so that it can yield to some extent after the capacity of thesprings J4 and t7'5 have been absorbed. After lthe leverj is4 moved tothe position as seen in Fig. 1 it is moved far enough rearward, so thatthe lug e2 can spring the chain and pass the end of said lever and againengage with it as the lug e2 is moved grainward. Next the lug e3 comesin contact with the stud t on lever t8, moving it along, moving thelower end of said lever t5 grainward, drawing the rod t9 in the samedirection, and thus unlocking the shaft o3. At this time the lug e2moves against the stud t on lever t2, moving it along, (stubbleward,) as

IOO

seen in dotted lines in Fig. 3, when it will spring the chain upward andpass the stud t. Said movement of lever t2 causes the shaft CZ to makeabout one-fourth revolution, which brings the needle or binder arm b5far enough down to grasp the grain brought in by the conveyer, as shownin dotted lines in Fig. IO. At this time the movement of the conveyer isreversed, and the pinion b', being now operated by the clutch b2 and inengagement with the cog-wheel b4, will rotate the latter until the blankbs is again opposite the pinion b', as seen in Fig. lO. The momentum ofthe cog-wheel bt causes it to move far enough to allow the pinion Z7 torotate in the blank bs clear of any friction until the shaft d is againstarted, as described. As the conveyer moves grainward, the lug e3 movesagainst the stud t', moving the lever t2 back again, as seen in fulllines in Fig. 3. Next it moves the lever s back again, as seen in Fig.3. Next the lug c2 moves against the lever j, moving it along, therebydrawing in the compressor in posi` tion, as seen in dotted lines in Fig.3. At this time the lug e* comes in contact with the lever I2, moving itstnbbleward, thus operating the discharger-bar and discharging the boundsheaf. As the roller I4 reaches the ends of the track i2, bent forward,the lever I2 will move forward and to an angle to the chain c', allowingthe lug c'l to spring the chain and pass the lever. At this time thegrainward movement of the conveyer ceases. As the conveyer is againstarted on its stubbleward movement, the lug e4 comes again in contactwith the lever I2, moving it grainward, thus drawing in thedischarger-bar in position, as indicated in Fig. 6.

Then the shaft CZ is started, as heretofore described, the cogs b9 willengage with the pinion b', the spring bl preventing any rearwardmovement of the shaft CZ, and when the movement of the conveyer isreversed the pinion b operates the cog-wheel b4, as described.

rlhe studs 15 and t are only indicated in Fig. 3, as they are on therear side of the levers t8 and t2.

The lever t2 when in position, as seen in full lilies in Fig. 3, restswith the lug tw against the post B6, and when moved, as seen in dottedsides in Fig. 3, it rests on a stud e, secured in a suitable position inthe sill B', as shown in Figs. l and 3.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-
